Wireless AP: AP is short for Access Point and is generally translated as "wireless access node", which mainly provides the access from wireless workstations to the wired LAN and from wireless workstations to wired LAN. In the coverage range of the access point, wireless workstations can communication through it. Commonly speaking, wireless AP is the bridge between wireless network and cable network. As the wireless AP coverage is a circular area that spreads outward, therefore, try to put the wireless AP in the center of the wireless network. And the line distance between all wireless clients and wireless AP should not be more than 30 meters to avoid communication failure resulting from excessively weakened communication signals.
